Ignition device of gasifier

Abstract

The invention discloses an ignition device of a gasifier. The ignition device comprises a fire-resistant plate, a heat insulation plate and an insulating plate which are sequentially overlapped from top to bottom, wherein a plurality of electric furnace discs are uniformly distributed in concave pits of the fire-resistant plate and are in threaded connection with wind shafts; convex rings are arranged at centers of the inner walls of disc covers and are 10-20mm away from arc-shaped ball heads arranged at top ends of the wind shafts; air outlet holes are arrayed in grooves of top ends of the disc covers and communicated with inner cavities of the disc covers; a plurality of inclined venting holes are arrayed in cylindrical walls of the wind shafts and communicated with middle air transmission holes; the wind shafts penetrate through the fire-resistant plate, the heat insulation plate and the insulating plate and are fixed on a wind chamber cover below; lower ends of the wind shafts extend into a wind chamber; a plurality of air inlet holes are arrayed in the cylindrical outer walls of the lower ends of the wind shafts and communicated with the middle air transmission holes; and the wind chamber is used for receiving air transmitted by a fan and transmitting air into the wind shafts. The ignition device disclosed by the invention has the advantages that gasification raw materials do not need to be tedded and dried in advance; and the whole combustion chamber is bestrewed with ignition points so as to guarantee that the gasification raw materials are ignited and burned thoroughly.

Description

technical field [0001] The invention relates to the technical field of a gasifier, in particular to an ignition device for a gasifier. Background technique [0002] We often see the smog of burning grass in the fields covering the sky, the waste residue outside the timber processing factory piled up like mountains, the husks of chestnuts harvested in mountainous areas are rotten enough to dye the creek, the inventor runs a township enterprise in 30 Over the years, I have been deeply touched by the surrounding environment. [0003] Gasification technology is a great invention, especially in today's society that pays attention to environmental protection and energy recycling, using straw, wood chips, garbage, clothing factory rags and other wastes containing combustible components, using it as fuel, for various The recycling of organic waste materials can also play a role in consumption, capacity reduction, and environmental pollution reduction.

AI Technical Summary

Problems solved by technology

[0004] Why has such a good technology not been widely promoted and applied in the market so far? Because most of the products in the prior art have the following fatal defects: 1. tar clogs the pipeline; 2. the water content in the waste is difficult to control, and the furnace is difficult to ignite; 3. About 20 minutes after the furnace was raised, the combustible gas discharged could not be ignited, and the green smoke filled the air; 4. The combustible gas was both flammable and explosive, and the safety was difficult to control

[0005] If these problems are not overcome, the masses will not accept them. For example, when the gasifier is raised, it is difficult to control the moisture content of straw, chaff, wood chips, etc., and it is necessary to put a lot of dry firewood underneath to ignite it. The energy first consumes a lot of high-quality energy, and the combustion chamber of the gasifier on the market burns unevenly, often the center is burned through the top, and there is still a large circle around it that is not burning. It is necessary to manually open the iron cover and use a stick to get inside Go and stir it up, very few people can stick to it for a full month
